DC brushed motor motor automatic pressure bearing magnetizing machine how to carry out maintenance?
1、Routine maintenance
l Cleaning
Equipment surface cleaning: After the end of each day's work, use a clean soft cloth to wipe the surface of the equipment, clear away dust, oil and other impurities. Pay particular attention to cleaning the surface of key components such as motors, sensors, control units, etc., to prevent the accumulation of dust affecting heat dissipation and electrical performance.
Internal cleaning (regularly): Every once in a while (e.g., one week or two weeks), open the equipment shell and use a compressed air canister or a small vacuum cleaner to clean up the dust and debris inside the equipment. For hard-to-reach nooks and crannies, a soft-bristle brush can be used for cleaning.
l Inspection of connected parts
Mechanical connection check: Check whether the tension of the transmission belt (chain) is appropriate, and whether there is any wear and tear, cracks and other conditions. At the same time, check whether the connection of gears, couplings and other transmission parts is firm, with no looseness or abnormal wear. For the mechanical connection parts of the pressure bearing and magnetizing mechanism, such as bolts and nuts, use a wrench to check their tightness.
Electrical connection check: Check whether the electrical connections, such as power cables, signal cables, and sensor connecting cables, are firm, and whether there are any signs of looseness, oxidation, or breakage. For plugs and sockets, make sure they are in good contact and can be plugged and unplugged appropriately a few times to remove the oxidized layer on the surface.
l Lubrication
Determine the lubrication point: According to the mechanical structure of the equipment, determine the parts that need to be lubricated, such as bearings, guide rails, screws and so on. These parts will generate friction during the operation of the equipment, and proper lubrication can reduce wear and prolong the service life.
Choose the right lubricant: According to the requirements of the equipment and the working environment, choose the right lubricant. For example, for bearings in high-temperature environments, high-temperature-resistant grease may be used; for guide rails operating at high speeds, low-viscosity lubricants may be required.
Lubrication operation: Lubricate the lubrication points regularly (e.g., weekly or monthly) according to the operation manual of the equipment. When lubricating, pay attention to the right amount to avoid too much lubricant causing pollution or waste.
2、Regular maintenance
l Mechanical components maintenance
Transmission system maintenance: Every certain period of time (such as three months or half a year), replace or adjust the transmission belt (chain). For gears, check their wear and tear, and replace them in time if they are badly worn. At the same time, clean and re-lubricate all parts of the transmission system.
Maintenance of the press bearing and magnetizing mechanism: Check the wear of the press head, tooling and other parts of the press bearing mechanism, and replace them in time if they are deformed or damaged. For the magnetizing mechanism, check the wear and performance of the magnetizing head, clean and calibrate the head regularly to ensure the magnetizing strength and uniformity.
Maintenance of positioning and clamping devices: Check the wear and tear of positioning and clamping devices such as positioning pins, positioning blocks and clamping jaws. Repair or replace worn parts. At the same time, check the positional accuracy of these devices and make timely adjustment and calibration if there is any deviation.
l Electrical system maintenance
Motor maintenance: check the wear of the brushes of the motor regularly (e.g. half a year), and replace the brushes in time when they are worn to a certain degree. At the same time, check the insulation resistance of the motor's windings and use an insulation resistance meter to measure the insulation resistance value to ensure that it is within the normal range. For the cooling fan of the motor, clean the dust on the fan blades to ensure good heat dissipation.
Sensor maintenance: Clean the surface of the sensor regularly to remove oil, dust and other impurities. Check the performance of the sensors, such as the accuracy of the position sensor and the accuracy of the pressure sensor. Standard testing tools and equipment can be used to calibrate the sensors to ensure the accuracy of their measurement results.
Control Unit Maintenance: Clean the control unit internally to remove dust and debris. Check the electronic components on the circuit board of the control unit for obvious signs of damage, such as bulging capacitors and burnt chips. At the same time, backup important data and programs in the control unit to prevent data loss.
3. Long-term maintenance (annual or according to the use of equipment)
l All check and calibration
Mechanical system calibration: Check and calibrate the overall mechanical structure of the equipment, including the positional accuracy and movement accuracy of each component. For example, use precision measuring equipment such as laser interferometer to measure and calibrate the straightness of the guide rails, flatness of the table, etc. of the equipment.
Electrical system calibration: All the parameters of the electrical system are checked and calibrated, such as the rotational speed and torque control parameters of the motor, the output signal range of the sensors, and the various setting parameters of the control unit. Professional electrical test equipment and calibration tools can be used for this work.
Adjustment of replacement plan for wearing parts: According to the operation of the equipment in the past year and the replacement records of wearing parts, adjust the replacement plan for wearing parts. For parts that are frequently replaced, analyze their causes, such as whether they are caused by quality problems, improper operation or poor working environment, and take corresponding measures, such as changing suppliers, strengthening operation training or improving the working environment.
Equipment performance evaluation and upgrading: Evaluate the overall performance of the equipment, including productivity, product quality, equipment reliability and other aspects. According to the evaluation results, consider whether it is necessary to upgrade the performance of the equipment, such as replacing better motors, upgrading the control software, improving the mechanical structure, etc., in order to improve the competitiveness and service life of the equipment.
